Category Archives: Post Exploitation

Every now and then I come across some application that may or may not have been developed with penetration testing in mind but it ends up being damn helpful all the same. Yesterday I found a post about ‘srvdir‘ (surv~durr?) which is designed to share content over SSL/TLS via a public site.

When trying to exfiltrate data from a client site I normally spend a lot of time setting up tunnels, using disposable A records from afraid.org and one of my boxes in some east-european cave just so I can get the damn ‘payroll-summary-june-2014.pdf’ trophy off some box that is swimming in ssh-tunnel-fu. srvdir is the perfect answer to this problem and testing it has been awesome and full of those “Why didn’t I think of this?!!” rants.

Essentially, what srvdir does is to create a SSL tunnel to the mothership ‘srvdir.net’ and issue a subdomain that can be accessed externally to siphon the files off. Grabbing files is relatively painless with the odd 404 for the permission snobs. … read more →

Often while conducting an internal pentest you may gain access to a user machine through some vulnerability or more commonly via social engineering. Let’s say that you pop a shell, unprivileged, and incognito only finds unprivileged domain tokens. You could move onto another target or you can try some post exploitation reconnaissance. A commonly overlooked source of sensitive information is documents that are stored on the company servers as well as staff who think they know enough to start sharing folders with their peers and end up sharing the root of ‘C’. These can be a fantastic source of juicy info if you know how to index and then search through them effectively.
